China now dominates the global gallium supply, accounting for about 99% of production. They made this happen by requiring domestic aluminum producers to extract gallium since the early 2000s and, more recently, by introducing export controls in 2023.
Gallium is a critical feedstock for compound semiconductors like gallium nitride (GaN) and gallium arsenide (GaAs). These materials power defense systems, robotics, electric vehicles, data centers, and advanced power electronics.
Innoscience’s rapid rise in GaN power chips has left many Western companies increasingly dependent on a single supplier. There’s growing talk about policy moves to boost domestic manufacturing and strengthen supply-chain resilience.
Global GaN supply and gallium: why it matters
The supply chain for gallium is extremely concentrated. Gallium comes as a byproduct of aluminum production, and China’s extraction policies have built a near-monopoly.
GaN and GaAs devices are now vital for low-voltage, high-efficiency power electronics. If gallium supplies get disrupted, it could hit strategic industries hard—from fast-charging stations to data-center converters.
These devices form the backbone of modern systems. So, gallium availability isn’t just economic—it’s a national-security issue.
With new export controls in 2023, gallium’s become a geopolitical bargaining chip. Western manufacturers now face tough questions: how can they secure upstream resources, dodge bottlenecks in GaN wafer supply, and ramp up local manufacturing before they get boxed in by a single dominant supplier?
China’s mastery and export controls
China’s game plan blends mandatory gallium extraction with strategic export controls. This move locks in supply for local needs and gives them leverage abroad.
That’s helped China stay on top in gallium, the key ingredient for GaN and GaAs semiconductors. The fallout isn’t just about price—it’s about who gets access to the latest devices for defense, telecom, and energy systems.
Export controls may slow outside access, but they also push others to find workarounds and build redundancy in the supply chain.
Innoscience: a leap forward in GaN manufacturing
Innoscience has taken the lead in GaN power chips by going all-in on a vertically integrated, fab-focused approach. They’ve poured resources into R&D, weathered unprofitable stretches to scale up, and received hefty state backing—over $350 million in subsidies.
Their high-yield production on 200mm GaN wafers—about 97% yield—shows they can deliver at scale. This gives them a huge cost edge over fabless Western firms like Navitas and EPC, making Innoscience a crucial link for Western companies needing foundry capacity.
But this heavy reliance on Innoscience creates a risky single-point dependency. If supply gets cut off, the fallout could be serious.
Patent lawsuits and ITC actions might slow them down, but they don’t really solve the problem. Manufacturers can still tweak designs or shift to importing finished products to get around restrictions.
Industry and policy implications for the United States and allies
The U.S. and its allies need a two-pronged approach: secure upstream raw materials and speed up downstream GaN manufacturing at home. Upstream efforts help buffer against geopolitical shocks.
Downstream investments let the U.S. and partners scale up 300mm GaN processes fast and build out full-stack solutions from IDMs.
Export controls on MOCVD tools might buy some time, but they’re not a long-term fix. What’s really needed is steady policy and funding support.
Public investment—think CHIPS Act funding—could help launch new fabs, boost yields, and cut time-to-market for U.S. and allied 300mm GaN tech.
Strategic actions to secure upstream and downstream resilience
- Secure upstream gallium supply by ramping up domestic mining, refining, and recycling, plus building strategic stockpiles where it makes sense.
- Advance 300mm GaN wafer manufacturing by supporting scale-up efforts at IDMs like Texas Instruments and Infineon. That way, they can quickly convert fabs and get better yields.
- Leverage export controls thoughtfully on sensitive MOCVD tools to buy time while the domestic ecosystem catches up.
- Drive ecosystem integration so there are full-stack GaN solutions—from raw materials to finished modules—cutting down on single-vendor risks.
- Align policy and practice with smart IP and trade rules that protect innovation and help avoid destabilizing supply shocks.
Path to resilience: policy levers and technology bets
Resilience comes down to efficiency and the depth of the ecosystem—not just raw capacity. If allied nations double down on upstream security and really push for downstream growth, they can shape a strong GaN-based future.
This approach lets them tap into GaN’s energy efficiency and performance perks. At the same time, they can manage geopolitical risks by spreading out supply and weaving in smart, integrated industrial policy.
